@sanity/debug-preview-url-secret-plugin

npm install @sanity/debug-preview-url-secret-plugin

This package is used together with sanity/presentation to debug URL preview secrets and their status.

Add the plugin to your sanity.config.ts:

// ./sanity.config.ts
import { debugSecrets } from "@sanity/debug-preview-url-secret-plugin";
import { defineConfig } from "sanity";
import { structureTool } from "sanity/structure";
import { presentationTool } from "sanity/presentation";

export default defineConfig({
  // ... other options
  plugins: [
    // ... other plugins
    structureTool(),
    presentationTool({
      previewUrl: {
        // @TODO change to the URL of the application, or `location.origin` if it's an embedded Studio
        origin: "http://localhost:3000",
        previewMode: {
          enable: "/api/draft",
        },
      },
    }),
    debugSecrets(),
  ],
});

You should see a new @sanity/preview-url-secret type in Structure Tool, which lists out secrets with metadata about when they were created and in what context.
